Poly(1-amino-9,10-anthraquinone-co-o-phenylenediamine) (P1AAQ-co-POPD) was synthesized by electrochemical methods on stainless steel electrodes (SS) using equal monomer concentration in acetonitrile/acidified water mixture as solvent. Electrochemical characterization allows, among others, determining the characteristic redox couple potential of the quinone group, which is one of the advantages of having achieved the copolymerization. FT-Raman, ATR and UV-Vis characterization confirms the formation of the copolymer, particularly, by the occurrence of a novel signal ascribed to a new C-N type bond. Besides, the conductivity of the deposits was determined, which enabled the conducting properties of the products to be verified. The topographical and morphological characterization accomplished by atomic force (AFM) and transmission electron (TEM) microscopy showed how the inclusion of o-phenylenediamine (OPD) increases the homogeneity of the copolymer, which in turn enables designing likely applications of the electrode modified with this novel polymeric material.
